On top of seemingly surpassing Tinder, SimilarWeb also found that as of Friday, Pokémon Go was already well on its way to meeting or even beating Twitter in daily active users on Android. For perspective, Twitter has been around for more than 10 years now. Specifically, around 3% of all Android smartphone users in the US are playing the game, whereas about 3.5% are actively using Twitter -- and those are just the numbers from late last week. Holy Crobat.
Of course, the analytics research doesn't account for the number of downloads and daily active users among iPhone users, but you can probably bet your Pikachu that it's pretty damn similar.
